I have been editing "Puzzle Corner" for more than 45 years. When I was a junior at MIT in 1965-66, I was asked to start the column for Tech Engineering News, a student run magazine, that is now defunct.
During the summer of 1966, John Mattill asked me to include
Puzzle Corner
in Technology Review, of which he was
the editor-in-chief.
For a few years Puzzle Corner
ran in both magazines and
continues to be published in TR.
TR has graciously permitted me to post back issues of the column. I am starting with 2002 and working backward. Click here to view the back issues (in pdf).
Starting academic 2000-2001, I have posted material that could not fit in the printed column due to space limitations. There is a firm limit of 2 pages for ``Puzzle Corner''. Please note that the problem is referred to by the issue in which it was posed, not the issue in which the solution was to appear.
